4. The aircraft inspection system according to claim 1 , wherein the at least one movable inspection unit is configured to verify structural features during the predetermined operating phase, comprising a landing phase and/or a takeoff phase, and to provide the inspection data relating to a load condition.

5. The aircraft inspection system according to claim 1 , wherein the at least one mobile inspection unit is configured as an aircraft-related inspection unit for at least one of: i) accompanying the aircraft and warn of bird strike and/or prevent bird strike during a predetermined operating phase comprising at least one of a landing phase and a takeoff phase; and ii) controlling an implementation rate of de-icing.

6. The aircraft inspection system according to claim 1 , wherein the unmanned vehicle unit is configured as at least one of: a drone flying along the aircraft; and a unit driving along the aircraft.

7. The aircraft inspection system according to claim 1 , wherein the position detection arrangement comprises a position measuring system configured for at least one of: determining internal position data within a mobile coordinate system in direct relation to the aircraft; and determining external position data within a fix local coordinate system in indirect relation to the aircraft.

8. The aircraft inspection system according to claim 1 , further comprising a communication device for feedback of the inspection data to a pilot and/or an operating system of the aircraft.

9. The aircraft inspection system according to claim 1 , wherein the at least one sensor is configured to implement at least one measuring principle from the following group: Thermography; Laser light sectioning method; Stray light method; Laser time-of-flight measurement; Image recognition; Pattern recognition; Magnetic resonance; and Triangulation, and wherein the at least one movable inspection unit comprises at least one sensor from the following group: Camera; Ultrasonic sensor; and Gas sensor.

11. The aircraft inspection system according to claim 1 , wherein at least one movable inspection unit is configured as a bi-functional unit, by which a determined defect can be repaired at least temporarily.

12. An aircraft comprising: an operating system for operating the aircraft; and an aircraft inspection system comprising: at least one movable inspection unit; a position detection arrangement; and at least one data transfer interface; wherein the at least one movable inspection unit: is configured as an unmanned vehicle unit which is movable in relation to an aircraft to be inspected during a predetermined operation phase of the aircraft, when the aircraft is not in parking position; comprises at least one sensor for: detecting a characteristic value, verifying a characteristic, and/or determining a defect of an aircraft; and is configured to generate monitoring data; wherein the position detection arrangement is configured to detect position data of the movable inspection unit in relation to the aircraft to be inspected upon detection of the characteristic value, the verified feature, or the determined defect, and to assign the position data to the monitoring data; wherein the data transfer interface is configured to provide the position data with the assigned monitoring data in the form of inspection data, and wherein the inspection data are taken into account for operating the aircraft.

13. The aircraft according to claim 12 , wherein the operating system comprises a central control unit; wherein the inspection data are supplied to the central control unit; and wherein the central control unit adapts the operation of the aircraft depending on the inspection data.

14. A method for inspecting an aircraft, the aircraft being in a predetermined operation phase, when the aircraft is not in a parking position, the method comprising: a) moving an unmanned movable inspection unit in relation to an aircraft to be inspected in the predetermined operation phase; wherein at least one sensor is provided for detecting a characteristic value, for verifying a characteristic, and/or for determining a defect of an aircraft; b) detecting the characteristic value, verifying the characteristic, and/or determining the defect by the sensor, c) generating monitoring data; d) detecting position data of the movable inspection unit in relation to the aircraft to be inspected upon detecting the characteristic value, in case of the verified feature, or in the event of the determined defect; e) assigning the position data to the monitoring data; and f) providing the position data with the assigned monitoring data as inspection data.
